Like our home planet, Jupiter has lightning and a magnetic field. So it is not surprising that sferics and whistler-like signals have been observed by Voyager and other space probes that have made close encounters with Jupiter.

Unfortunately, low-frequency signals from Jupiter cannot penetrate the Earth's ionosphere and thus cannot be detected by terrestrial observatories.

However, the planet Jupiter emits radio waves in the 20 Mhz. region that are easily received on Earth with relatively simple equipment.
